As I scrapped my forever games and restarted fresh, I stumbled across the awesome work made by Pjranha and Normi1701 from the Top Of The Galaxy hub. They made a map of one planet, to find 14 glyphs! You just need to portal in (to a 2-glyph planet, yup - you need to get 2 glyphs first), build an exocraft and bobs-your-uncle! Oh, the planet is GORGEOUS with rolling hills and crevices that are VERY friendly to reckless driving!! I can’t recommend this game-within-a-game enough! Thanks to CobraTV for making a video of it! Here is Cobra TV giving an intro and Here is the fact page from T.O.G. hub.
Bonus: By attaining all the glyphs in one sitting, you also get a good feel for the lore of the game overall. The dead travellers have a real story to tell!
